The safety video display unit (SVDU), as the display machine of the reactor protection system, performs the functions of displaying the reactor’s safety parameters and sending safety control commands. In order to meet the needs of nuclear power safety-level digital control system (DCS), like designing verification, operator training, and accidental drills, for the SVDU in the NASPIC platform developed independently by China National Nuclear Corporation, a virtual embedded system technology based on the micro x86 industrial host is proposed to make software simulation to the SVDU physical controller with exactly the same hardware appearance of the original one. The SVDU stimulator realized by this research can achieve 100% simulation of the logical functions of the SVDU physical equipment and the synchronized upgrading function between stimulator and the real equipment. With the development of multiple engineering application requirements, such as configuration verification and operator training, this stimulator has been applied in several virtual security level DCS projects.

基于仿真技术的SVDU模拟器的研究与实现

安全视频显示单元(SVDU)作为反应堆保护系统的显示机,执行反应堆安全参数的显示和安全控制命令的发送功能。为满足核电安全级数字控制系统(DCS)设计验证、操作员培训、事故演练等需求,中核集团自主研发的NASPIC平台上的SVDU,采用虚拟嵌入式系统技术提出基于micro x86工业主机对SVDU物理控制器进行软件仿真,硬件外观与原控制器完全相同。本研究实现的SVDU刺激器可以实现对SVDU物理设备逻辑功能的100%模拟以及刺激器与真实设备的同步升级功能。随着配置验证和操作员培训等多项工程应用需求的发展,该激励器已在多个虚拟安全级别的DCS项目中得到应用。
